Iowa's presidential caucuses are any Republican candidate's to win. Just two months before the GOP nomination voting begins, Iowa Republicans aren't surging toward former Massachusetts Gov.

And, this time, none of his opponents has emerged as the consensus candidate of conservatives _ and, thus, Romney's chief challenger _ the way Mike Huckabee did four years ago.

WASHINGTON (AP) — A White House adviser say Mitt Romney has "moved all over the place" on issues from abortion to gay marriage over his career and might not have firm enough convictions to make the tough decisions as president.

David Plouffe (pluhf) jokes that if Romney thought "it was good to say the sky was green and the grass was blue to win an election, he'd say it."

Plouffe, who was Barack Obama's 2008 campaign manager, notes a new Iowa poll showing Herman Cain leading with 23 percent support, and Romney next at 22 percent.

Plouffe tells NBC's "Meet the Press" that Cain "seems to have tapped into something." Plouffe says lots of voters still are "looking somewhere else" beyond Romney and he wonders whether the early front-runner can turn that around.
